Let me preface this post by saying I have absolutely no idea why Milan Hejduk's post-goal impersonation of a swimmer is called "The Duck Dance." It bears no resemblance at all to anything duck-related, other than the fact that ducks also swim.
Also let me preface this post by saying the video quality in the clip below is of substandard value, but the action is still relatively visible and the audio's not horrible.
So, without further prefacing, please enjoy the following video of Milan "The Duke" Hejduk celebrating a goal in a truly unique way.
Classy.
